Abstract
Official abstract text for this publication.
Methods, systems, and apparatuses are provided for performing jitter buffer enhanced joint source channel decoding. Jitter buffer enhanced joint source channel decoding may be performed in a manner that exploits parameter domain correlation. A jitter buffer stores hard bits of properly channel decoded packets, and a secondary jitter buffer is implemented to store soft bits associated with packets that are improperly channel decoded. Joint source channel decoding may be delayed to perform channel decoding of a frame in the penultimate position of the jitter buffer. The soft bits stored in the secondary jitter buffer as well as hard bits stored in the jitter buffer, which may include future frames, are utilized to perform channel decoding. The delayed jitter buffer enhanced joint source channel decoding may also be extended to iteratively perform channel decoding for giving frames at each position in the jitter buffer as they traverse the jitter buffer.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: storing a plurality of hard bits in a first memory buffer; storing a plurality of soft bits in a second memory buffer; and performing joint source channel decoding on a first subset of the plurality of soft bits based upon one or more of at least a portion of the plurality of hard bits and a second subset of the plurality of soft bits, the first subset being associated with a first segment of an audio signal, and the one or more o…
